    DC/DC Converter (the proper diode)

    Hi there. Looking at the schematic (http://cds.linear.com/docs/Datasheet/3471fb.pdf) on page 16, I am asking myself what kind of diodes are recommended for a boost topology. It is certain that it should be a fast switching diode, its capacity should be as low as possible. What I am in doubt of...

    Dual Supply Boost/Inverting Conver

    Hi there. Looking at page 16 of this datasheet: http://cds.linear.com/docs/Datasheet/3471fb.pdf I am wondering if I could lower the Voltage at pins 10 & 6 using some diodes in series. Why I want to do so: (Just looking at one part, namely the positive voltage) The internal switching...

    Potential free USB ?

    Hello out there. I am wondering if I could build some device based on optocouplers (or other solution), to seperate a USB device from the PC to make it potential free. Of course the device to be seperated could not be powered via USB. In other case I would be forced to use at least a...

    3 x Inductance one core

    Hello. I am looking for a Inductor which I want to use in a SEPIC DC/DC Converter. What I need are thre coils (each 25uH) at one core. Saturation current and resonance frequency are not exactly specified yet. After simulating the whole thing with LTspice I_sat turned out the be about 9A. Not...

    LT3757 as SEPIC Converter

    Hello. If You look at Page 32 of this Datasheet: http://cds.linear.com/docs/Datasheet/3757fa.pdf, there is the LT3757 as a SEPIC Converter, delivering +-0.4A at +-12V. Could You tell me if it
